Specification of Letters Patent.

Application filed December 5, 1914, Serial No. erases Renewed. April 6, 1917. Serial no. 160,311.

To all whom it may 0011061 11:

Be it known that I, GUSTAV DREws, a citizen of the United States, residing in New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Book-Supports, of which the following is a specification.

This invention relates to and has for its main objects to provide a book support that will hold an open book at an angle in position for reading; also to provide a device that can be folded together thus to facilitate shipping, and for the convenience of home or oliice to pack away in a drawer or on a library shelf; it is also intended to provide a device that is made of substantially two pieces, and one that will support itself in open position at the proper angle without the use of any breakable parts; and it is further intended to provide a means for holding down the leaves on such support.

A specific construction embodying this invention is illustrated in the accompanying drawings in which Figure 1 is a view in perspective of an embodiment of the invention in open position.

Fig. 2 position.

Fig. 3 is an end view of the same in closed or folded up position.

Fig. at is a plan view of one section of the support detached.

Fig. 5 is a cross-section on the. line 5-5 of Fig. 4. e s

Fig. 6 is a plan of one section of a modification; and Fig. 7 is a crosssection'of the same on the line 77 of Fig. 6. I

In the construction shown, two plates 5 and 6 are hinged together by hinges 7 and 8. These hinged plates may be of wood or stamped, out or cast out of metal. In conformation, they are practically identical, so it will suffice to describe but one of them. A rear extension 9 is provided, substantially triangular, the base 10 of which extends from the middle of the main plate, the hypotenuse 11 extending from the outer edge of the base to the outer edge of the main plate, thus leaving a right angular recess as clearly shown in Fig. 4. The edge 12 of the main plate in this recess or cut-away portion is beveled. WVhen the device is open for use, this beveled edge 12 rests against the extension 9 of plate 5. These beveled edges 12, 12 resting against the extensions 9, 9

is an end view of the same in open actually receive the load carried by the support, thereby saving the hinges and incidentally serving to give a neat, closefitto the support when opened, and to permit free operation of the hinges. The portion of the support resting on the. table is 'a-corne'r of one of the extensions and the hypotenuse 11 of the other extension. lAs is-obvious, by making these plates witlrtlieir extensions identical, the support can be reversed and set up in position, the same one way as the 7 other; I

To prevent the book from slipping down onto the table, ledges 13 may be provided.

These can be provided at the upper and lower edges of the plates for the purpose of using the support as a reversible device. In

the present instance, ledges'13, 13 are'provided only at the lower edges of theplates.

Obviously if the device is not to be used as 'a reversible device, the conformation of one of the. extensions 9, the one'which when in use only engages theresting surface with its corner, may be of any other suitable conformation.

It is also to be noted that the inclination of the support may be adjusted as desired by merely changing the length of one extension or by changing the length andinclination of the hypotenuse of the extensions, or by placing a book or other object under the corner of the extension.

A means for holding downthe leaves of the book are provided. In the construction shown, there is provided a portion 14 rolled over from each of the ledges 13. In this portion 1-1 is pivotally secured the end of a wire 15. When the book is folded up, these wires are turned down below the lower edges of the plates. lVhen the book is open, the wires are turned up to engage any part'of the leaves. these wires may be positioned between the plates 5 and 6, the tail pieces 16 serving to springpress the wires in closed position.

Obviously when the device is made of sheet metal as shown in Figs. 6 and 7, a rolled formation 12 is substituted for the beveled edge 12, of the construction shown in Fig. l, and a hinge portion 7 is formed integral with the main plates, instead of using separate hinges.

Although but one specific embodiment of this invention is herein shown, it will be understood that numerous details of the construction, shown could be altered or omittedv When the support is closed,

without departing from the spirit of this invention.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is:

1". A support comprising two plates hinged together, each plate having a rear extension, the extensions passing" one an other when the plates are opened into supporting position, a portion of each plate extending across and resting on the rear extension of the other plate when the plates are opened so that the plates lock one another inopen position: I

2. In a book support comprising two plates hinged together, each plate having an extension extending from one-half of the rear edge of the plate, saidextension being of triangular conformation, the remaining half of each plate extending across and resting-Lon the extension of the other plate when the plates are opened so that the plates lock one another in open position. I

3.1a a book support comprising two p'lates'hinged together, each platehaving a rear extension in its plane inthe form of a right-angled triangle projecting fromthe hinged edge of the plate for half the length of said edge, the hypotenuse forming one of the sides of the projection, the plates in open position resting on these rear extensions,*one ofjthe extensions adapted to engage the resting surface with its corner and the other extension adapted to engage the resting surface with its hypotenuse.

4:. A reversible book support comprising two plates pivoted to one another, each plate having a rear extension,the rear extension being of right triangular conformation so that when the support is open both the corner of one of the" extensions and the hypotenuse of the other engage the resting surface. 7

Q 5. A book support comprising'two plates hinged to one another, a rear extension on each plate, a portion" of eachlplate resting on the rear extension of the other plate when the plates are openedso that the plates lock one another in open position, means preventing the book supported from slipping down, and means for holding the leaves.

Copies 0! this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

folded together, said support comprising two plates pivotally connected to one an other along'opposing edges, said plates having rear extensions extending'froni said'o'p' posing edges and in the planes of'said plates, the extension's'each havingfone side beginning substantially at the middle of the. edge from which it extends, said platesin open position being supported by said extensions, each'of saidextensions extending under and'across the opposing edge of the other plate and contacting with the same,

the extensions thus also acting asstops to prevent the plates from swinging" clear around on theirpivotal connection but look them at an angletoone another where they are ready to receive an openbook;

8. A' book support comprising plates pivotally connected to one another warmestensions 011 saidplates, the extensionspassingone another when the plates ar'eopen'ed into supporting position, and portions of' the plates extending across and resting on said extensions when the plates are opened so that the plates lock one another in open position.

9. A book support comprising plates anchored to one another and rear extensions on said plates, the extensions projecting in different directions, and the plates extending across and, resting on said extensions in supporting positionso that the plates lock one another.
